STEAM-HEATING APPARATUS.

Specification of Letters Patent No. 29,932, dated September 4, 1860.

T0 all whom t may concern:

Be it known that I, CHARLES A. IVILSON, of Cincinnati, Hamilton county, Ohio, have invented a certain new and useful Improved Radiator for Steam-Heating Apparatus; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

'Ihe object of my invention is a more efiicient application of low pressure steam to room heating purposes and consists in a peculiar arrangement of upward branching coils or pipes and discharging valves as hereinafter set forth.

rIhe portability, eXtreme facility of construction and repair, and the easy adaptation to particular circumstances and require ments, of wrought iron pipes would it is thought, have caused their more prevalent adoption for room warming, but for the fact that steam, of the desired low temperature, is so nearly in equipoise with the atmosphere, that it does not readily or certainly pass by or displace the air, confined within such narrow and elongated passages; and hence, while one portion has become charged with steam, another portion, remaining full of air, has proved wholly or partially inoperative. These defects I have now eflectually remedied by an arrangement of ascending coils or branches which communicate with the main pipe by their lower ends alone, so as to permit the discharge of condensed water and the entrance of unbroken columns of steam through their lower ends; accompanied by a simultaneous escape of air into the room from their extreme upper ends, by means of valves one to each coil or branch which close or contract automatically as each particular branch becomes charged with steam.

In the accompanying drawings Figure l is a perspective view of a simple and Fig. 2 of a compound radiator illustrative of my invention. Fig. 3 is a section on a large scale of one of the air valves or thermostats.

A is a portion of the main steam pipe furnished with a cock a, and communicating with either' av simple radiator as shown in Fig. l or by means of suitable coupling B with a compound radiator D shown in Fig. 2. Flach. coil terminates above in a flat tube E the respective sides of which are composed of strips of steel and brass or other metals of unequal expansion constituting a thermostat which discharges through a nipple F which when the tube is deflected by the entrance into it of steam from the coil comes in contact with an adjustable plug Cr and thus closes the coil. Upon opening the cock a steam enters the coil C or D, forcing out the air through the thermostat E F until the latter is filled with steam when the vent is closed automatically as before stated. 'Virater of condensation iiows back to the boiler through the pipe A by its own gravity. By adjustment up or down of the plug G any desired heat or moisture may be thrown into the room.

It will be observed that the construction and arrangement of this radiator are such as to afford to every part the utmost freedom to expand and contract in accordance with changes of temperature.

I do not desire to confine myself to any particular form of radiating tubes but have represented in the present illustration a coil form which is advantageous in affording large heating surface within a small space and at the same time permitting the free return of water of condensation to the steam pipe A and thence to the boiler.

claim as new and of my invention herein,

A tubular radiator communicating at bottom with a steam'pipe A and at its upper and free end'discharging into the atmosphere through an aperture, guarded by an automatic valve the whole being constructed and operating' substantially as and for the purposes ,set forth.

In testimony of which invention, I hereunto set my hand.
